M. LEVlTlN Feb. 6, 1951 CHAIR Filed June 30, 1947 INVENTOR. M02221?! Leuzfz'n,

ATTEJ R N EYE Patented Feb. 6, 1951 3 Claims.

My present invention relates to an improved chair and more particularly to a chair for children and adapted to be supported upon the seat of a conventional chair as of the dining room type, and includin construction features by means of which the height of any chair may be varied.

The chair of my invention has many uses and may be employed to advantage with conventional chairs as in dining rooms, or it may beused as a unit, as desired.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claims.

In the drawings:

Fig. 1 is a side elevational view of the chair of my invention shown mounted upon the seat of a conventional chair.

Fig. 2 is a side elevational view of the chair according to my invention.

Fig. 3 is a front elevational view thereof.

Fig. 4 is a vertical sectional view at line 44 of Fig. 2.

Fig. 5 is a view in perspective of the disassembled elements of the chair.

Fig. 6 is a detail view of the securing construction for the separable elements.

Referrin now to the drawings wherein I have illustrated the present preferred embodiment of my invention, I have shown a chair having a seat 2 and back 4 supported upon legs 6, braced at 8.

The chair of my invention comprises a seat panel l0 and back 12 with arms l4 on posts l6, and a strap l8 may be detachably secured between the posts by hooks 20.

Beneath the seat panel I0 I provide front and back frames or flanges 22 and 24 connected by brace 26 and the bottom edges of these frames are grooved at 28.

This chair may be used separately if desired, but to afford greater height I employ a box or frame having front and back frames or panels 3!! and 32 and side bars 34 and 36 braced at 38, and the upper edges of the frames 30 and 32 are ribbed or tongued at 4!] for interlocking attachment with the grooves 28. The under edges of the frames 30 and 32 are also grooved as at 42 and a similar box having front and rear frames 44 and 46, and side bars 48 and 50 braced at 52 I UNITED STATES PATENT OFFICE CHAIR Manuel Levitin, San Francisco, Calif.

Application June 30, 1947, Serial No. 758,072

The upper edges of the frames 44 and 46 are ribbed at 54 to interlock with the grooves 28 or the grooves 42.

The chair of my invention may be assembled with either or both of the open box frames thereunder and the tongue and groove interlocking arrangement will prevent the sections from sliding forward or backward should the child rock back and forth as children often do.

The chair of my invention offers a simple and inexpensive solution to the high chair problem and of course the height of the chair may be reduced as the size of the child increases.

Having thus fully described my invention what I claim as new and desire to secure by Letters.
